Filter by:This study aims to investigates the role of gestational age on the prevalence of coagulation factors and components of the complement system in preterm- (≤32+0 weeks) and term neonates (≥37+0 weeks) and their role for the development of brain hemorrhage.
This study will evaluate the impact of matching donor human milk to the maternal secretor status of very preterm infants (<34 weeks gestation) on the gut microbiome. Half of enrolled infants will receive donor human milk which is matched their mother's secretor status and half will receive standard (unmatched) donor human milk, which is standard care in the neonatal intensive care unit.
CRAFT-OBS: Observational Study; To evaluate subsequent pregnancy risk of preterm birth in women with a history of previous caesarean in established labour. This prospective study using clinically acquired cervical length and quantitative fetal fibronectin data will help establish a predictive model of preterm birth <34 weeks and <37 weeks. CRAFT-RCT: Randomised controlled trial arm; To assess treatment for short cervix in women at high risk of preterm birth following a caesarean section at full dilatation CRAFT-IMG: Imaging sub-study; To aid understanding of micro and macrostructural features within the cervix which predisposes to preterm birth in women with a previous full dilatation caesarean section. This will use MRI and an advanced transvaginal ultrasound protocol and to assess if structural changes can be visualised in the cervix.
Uterine septum is the most common congenital uterine malformation. It accounts for approximately 35% of all uterine malformations, while the frequency of uterine malformations in the general fertile population is estimated to be between 1% and 4%. The presence of a uterine septum is associated with subfertility and a high incidence of obstetric complications, such as spontaneous abortion, 3-fold increase in preterm premature rupture of the membranes (PROM), 6-fold increase in preterm delivery, malpresentation at delivery, caesarean section, and increased perinatal morbidity and mortality. Some studies have found that surgical resection of the uterine septum improves pregnancy outcomes and significantly reduces the risk of preterm delivery. Therefore, the risk for a short-term adverse outcome and long-term sequelae due to preterm delivery such as intraventricular hemorrhage, necrotizing enterocolitis, sepsis, patent ductus arteriosus, retinopathy, deafness, chronic lung disease, cerebral palsy, perinatal death, and impaired mental development in women with uterine septum could be lowered by performing a relatively simple and safe hysteroscopic septum resection (HSR). However, there are two major concerns regarding HSR: cervical incompetence due to excessive dilatation during hysteroscopy and the rare yet serious complication of uterine rupture in subsequent pregnancy or delivery. Considering these elements, the aim of this study will be to evaluate the rate of preterm delivery in singleton pregnancy comparing primary infertile women who underwent HSR and who did not undergo the same procedure, with our without in vitro fertilization.
The purpose of the PIINC study is to identify differences in placental inflammatory lesions between women participating in group prenatal care versus standard prenatal care, and additionally, examine whether the frequency of placental inflammatory lesions differ by race and income. The investigators hypothesize that women participating in group prenatal care will have lower pro-inflammatory profiles compared to women in routine prenatal care.
In some studies of fetal thymus volume, fetal stress factors; infection, preterm premature premature rupture of membranes, preeclampsia, preterm delivery risk. Generally, there is a direct correlation between fetal growth and thymus volume and it was observed that thymus volume decreased in pregnancies accompanied by fetal stress factors.The aim of this study was to measure fetal thymus volume in second trimester twin pregnancies and to investigate whether there is a statistically significant correlation between preterm birth risk pregnancies.
Twin pregnancies are associated with increased risk of perinatal adverse outcomes , including preeclampsia , fetal growth restriction , preterm premature rupture of membranes and preterm birth. Low-dose aspirin was recommend by American College of Obstetricians and Gynecologists (ACOG) during pregnancy. In this trial, the investigators suppose that aspirin used in twin-pregnancies could improve adverse pregnancy outcomes.
This study is a non-blinded, prospective, randomized controlled trial designed to compare the effect of outpatient oral antibiotics (i.e., amoxicillin and azithromycin) on the length of time (days) that pregnancy continues after a patient's water bag has ruptured prematurely. If a patient has been diagnosed with rupture of their water bag between 18 0/7 weeks and 22 6/7 weeks and there are no other associated complications with the pregnancy, the patient is eligible for initial consideration for this study. Patients will be admitted to the hospital for a 24-hour monitoring period. If the patient remains without further complications during this monitoring period, the patient will be eligible for enrollment. If enrollment is desired, the patient will be randomly assigned to receive either antibiotics (treatment arm of the study) or no antibiotics (control arm of the study). The treatment arm will receive an outpatient, 7-day course of oral antibiotics (azithromycin and amoxicillin) with the first dose given in the hospital to ensure no side effects. The control arm will not receive outpatient antibiotics. Both groups will have weekly, office follow-up visits with high-risk pregnancy specialists to ensure no further complications. Both groups will be admitted to the hospital if the patients reach 23 0/7 weeks without complications. At this time the patients will receive all medications and therapies recommended by the governing board of OBGYNs. Subjects of both groups will also be admitted before 23 0/7 weeks if further complications noted either at their clinic follow up visits or anytime outside of the hospital. The duration of time that the patient remains pregnant after breaking of the water bag will be compared in each group. The investigators will also see if there is a difference in the number of patients able to reach 23 0/7 weeks between each group (treatment versus control).
The aim of this data base is to know exactly the future of a "vulnerable newborns" cared in Pontoise Hospital (In the neonatology service) and compare the information with the national data of preterm birth.
Every year, globally, about 15 million babies are born preterm (before 37 weeks). This number is rising. Preterm birth (PTB) complications are the leading cause of death among children under 5 years of age, responsible for nearly 1 million deaths annually. PTB poses a strain on scarce health resources: each very premature baby costs tens of thousands of pounds in newborn care. One in 4 babies born before 28 weeks develop neurological impairment, a parent often having to give up work to care for an affected child. The prediction and prevention of PTB remain challenging because current methods, such as measuring the cervix by ultrasound, have limited accuracy. If a technique that reliably predicts PTB could be developed, there are care measures that can be employed to delay birth to reduce long-term disability/impairment. The Investigators have been studying whether they can detect the changes in cervical tissue structure and composition that precede PTB by using very low current Electrical Impedance Spectroscopy (EIS). Evidence recently showed that women at high risk of PTB (history of previous PTB), who deliver preterm, including delivery before 28 weeks gestation, have lower cervical "resistance" in mid-pregnancy than those who deliver at term. With NIHR funding, the investigators have developed a new device, based on a technique called magnetic impedance spectroscopy (MIS) that should address limitations of the EIS device for assessing PTB risk. The investigators now want to refine the new MIS device by minimising the signals it receives from other tissues around the cervix and making its measurements at internal body temperature more stable. The researchers also conduct clinical experiments to test whether it predicts PTB better than the previous EIS device, and check whether pregnant women find its use acceptable. This information will allow them to obtain UK regulatory approval to test the device in larger trials.
